Your digital nutritionist

While diet and nutrition apps abound, logging adherance and any sustained benefit for weight loss using these technologies remains low. The authors believe, however, that smartphones have potential value beyond diet logging. "By synchronising various health data types from multiple sources, such as wearable sensors, electronic health records, metabolic profile, gut microbiome, and diet, all analysable in real-time using machine or deep-learning algorithms, a person's smartphone has the potential to function as a digital nutritionist."
